Answer:

20

Step-by-step explanation:

the comment below or above me has everything right except one thing. 4 plus 2 plus 3 equals 9, Not 10. 180 divided by 9 equals 20 and there's your answer

All the interior angles of a triangle always add up to 180 degrees.

3x + (2x + 20) + (4x - 20) = 180
3x + 2x + 20 + 4x - 20 = 180
3x + 2x + 4x + 20 - 20 = 180
10x = 180
x = 180/10
Therefore, x = 18

Which sequence is geometric and which is arithmetic?
tekilochka [14]

The table on the left is <u>arithmetic</u>

This is because each term is increasing by the same amount (2) each time.

  • 3+2 = 5
  • 5+2 = 7
  • 7+2 = 9
  • 9+2 = 11

--------------------------------------------

The table on the right is <u>geometric</u>

Why? Because this time we are multiplying each term by the same value (2) to get the next term.

  • 3*2 = 6
  • 6*2 = 12
  • 12*2 = 24
  • 24*2 = 48

Both involve the number 2, but the first table uses addition while the second table uses multiplication.

I assumed that you wanted to know how much little cubes are in the big cubes...so.....first you need to find out the volume of the small cube : 1/2 x 1/2 = 1/4....then divide it with 10, then results with 40! :D
